BOLTLESS ANTICREEPlING DEVICE FOR RAILROAD RAILS.

Application filed August 2, 1.923. Serial H0. 855,273.

To all whom it may concern Be it known that l, Anonnmnr J. Co K, acitizen of the United States, residing at ester-lo, in the county ofAlbany, State of New York, have invented certain new and usefulImprovements in Boltless Anticreeping Devices for Railroad Rails, ofwhich the following is a specification sufiiciently full, clear, andaccurate as to enable those skilled in the art to make and use the same.

The object of the invention is the provision of a device which whenseveral thereof are combined with track rails and cross ties willprevent the creeping or longitudinal movement or" therails relative tothe ties an der trallic. Its function is to hold the rail in a fixedposition relative to the tie so the force which causes creeping will betransmitted through both the rail and tie to the track ballast.

The invention consistsin certain novelties of construction andcombination of parts as herein set forth and claimed.

The accompanying drawing illustrates an example of the embodiment of theinvention constructed and the parts combined according to the best modeof procedure I have so far devised for the purpose.

Figure I is a. view in perspective of a track rail and tie with myimproved anti crecping device combined therewith.

Figure 2 is a side elevation of a metallic plate partly fashioned Figure3' is a perspectivelview partly in section of the locking wedge whichwith the plate constitutes the entire anti-creeper.

Referring to the several figures, 5 designotes the connnon railroad railhaving l'langes'fi, 6 with top inclined surfaces; 7, a common form oftie in practice partly enihcdded in track ballast: i, the vertical surfaceof one side of the tie; 9,.the fashioned plate forming part of theanti-creeper: 10, dotted line. the line on which bent or turned to aninverted l.) shape, as shown by Figure 1: 11, the edge of the plate; 12,two jaws at the edge of the plate and at opposite ends, each jaw havingan inclined under surface 14 to match the inclined surface of a railflange; 15, a metallie locking wedge of a general U shape in, crosssection providing a recess or channel to receive the edge 11 of theplate, as show 18, one end of surface at the end of the wedge inside theto serve as an element of the entire device.

. load; the application of the the plate is the wedge; and 17 is abeveled.

channel'to facilitate the movement of the same along the edge 11 of theplate when the wedge is being driven into position. v

To apply the device, first, the plate is slipped over the end of therail before the same is secured to the ties so the jaws 12 will overlapthe flanges 6 of the rail, the beveled surfaces 14 of the jaws matchingthe top beveled surfaces of the rail flanges, and the side of the platefrictionally engaging a vertical surface Slot a tie; and, secondly, thelocking wedge 15 is driven into position along the under surface of thebase of the rail and with the edge 11 of the plate seated within thechannel in the wedge and frictionally engaging the metal defining thesaid channel.

As the plate 9 is of spring metal preferably, the insertion of the wedgedraws the jaws down upon the flanges of the railand linsures a firm andsecure grip. Obviously, jwhen a train passes over the rail, and thejforce thereof tends to move the rail relative -t0 the tie, the grip ofthe jaws will be increased, inasmuch as the plate bears against 'thevertical snil ace 8 of the tie.

From the foregoing description taken in connection with the drawing itwill be that l have devised a holtless anti-creeping- ,device for railswhich will perform the requisite function or" holding the rail in placerelative to the tie.

The general causes of rail creeping are: the Wave motion of the trackunder the alternate application and release of a rolling brake,especially when the wheels slide; curvature of the track when thevelocity of the train er or less than the velocity for outer rail iselevated; and

A plurality of my devices in use will. an chor the rails to the'ties sothey cannot move relative to the ties, and consequently the force orforces which cause creeping must be transmitted to several ties at thesame time and at difierent points, thus distributing the energy moverelative to the track ballast.

Vl hat I claim is:

1. An anti-creeping device for rails con; sisting of a metallic platehaving jaws at one edge and the opposite edge disposed eral leiwi-th'ancl in a plane below the jaws, and a locking wedge adapted toengage the said edge and the base of a rail.

J3- deseenenig so the rails and ties will not Mil not

2. An anti ereeping device for rails consisting of a metallic platehaving two parallel edges one of the edges being provided with jaws, anda locking wedge fashioned to engage the other edge of the piate and thebase of a rail.

3. The subject-matter of claim 2 said iock-' ing Wedge having a channel.to receive the edge of the plate.

4. An anti-creeping device for rails consisting of a plate substantiallyU-shapcd in cross section one edge only thereof being provided with'a\\'s, the other edge hein; located below t 1e said jaws, and a wedgeadapted to engage the said plate and the base of a rail.

5. An anti-creeping device coneistingofesa-e16 two elements eachsubstantially Jrshaped inelement.

6. The combination with a rail and tie, of an anti-oreeping devicecomprising two parts one part being of spring metal U shaped in crosssection, one edge only having' a single pair of jaws engaging theflanges of a rail and a surface engaging one surface of the tie, and theother part engaging'i'he said first mentioned part and the base of therail with a wedging aciion which forces the jaws against the flanges ofthe rail:
